Which weapon system is heavier, the Mauser or the GAU-22A?

The Mauser, specifically referring to variants like the Mauser 20mm cannon, generally has a heavier weight compared to the GAU-22A. The Mauser systems are designed for high-caliber, high-velocity projectiles and typically have a more robust construction to handle the increased pressures associated with larger rounds.

In contrast, the GAU-22A is a four-barrel 25mm revolver cannon that, while designed for versatility and reliable performance in various aircraft, is comparatively lighter due to its smaller caliber and the use of modern materials aimed at reducing overall weight. This makes the Mauser, particularly in its larger configurations, the heavier option.

Understanding the context of these systems shows that they are designed for different roles; the heavier Mauser is often found in anti-aircraft and ground-attack roles, while the GAU-22A, being lighter and more compact, is suited for use on modern tactical aircraft, where weight savings can significantly impact performance.
